Specification of Letters Patent.

Application filed September 1, 1916. Serial No. 118,025.

To all whom it may concern:

Be it known that I, LEWIS Corinna citizen of the United States ofAmerica, and a resident of Chicago, county of Cook and State ofIllinois, have invented certain new and useful Improvements inPhonographs, of which the following is a specification.

This invention relates to phonographs' suitably arranged for use in toysand other devices, such as cigar cutters, clocks, dolls, savings banks,etc.

The objects of the invention are to provide simplified and improvedmeans for starting, stopping and governing the speed of devices of thisclass; to provide improved means for automatically disengaging the 7tion.

This invention provides simplified and improved devices in the structureof small phonographs whereby the same may be pro.- duced at low cost,but still permit of a great number of operations thereof without anyappreciable deterioration of'the mechanism.

Power is supplied to the device by means of a small clock mechanismincorporated therein and comprising gears 1 to 6 inclusive, connecting aspring motor 7 with a rotatable record'support 8. The record sup port 8is fixed to a sleeve 9 surrounding a winding spindle 10 journaledtherein. The

rotating. the gear and servesto drive the winding of the spring. Theouter end of the spring 7 is secured to a tie rod 12 Fig. 3. For thepurposeoflimit- 'ing the winding of spring '7, spindle 10 carries fastan arm 13 in position to engage a fixed stop pin 14, Fig. 6.

' The starting and stopping and the speed of the device are controlledthrough a governor 15. The latter comprises a spindle 16 to which aresecured pinion 17 and arm 18.

The pinion 17 receives motion from the gear 5 with which it meshes, atsuch speed as to cause the small weights 19 of the'governor tobecomeeifective in shifting a disk 20 slidable on spindle 16 intoengagement with pad 21, against the. action of spring 22 surrounding thespindle. The weights 19 are supported in balanced relation by thepivoted links 23 connecting arm 18 with disk 20. Longi- .with more orless pressure, and

tudinaltlfiaist of spindle 16. is prevented by springs 24 hearingagainst the ends of the spindle and supported byathe frame plate 25 andbracket 26 on frame plate, 27.

The sound reproducing disk 28 is mounted in the sound box 29 supportedon frame plate 27. The disk or diaphragm 28 has attached centrallythereto a wire 31 connecting itto a pivoted stylus arm 3 2,'the latterbeing provided with a jewel tip 33 for engagement with record surfaces.The stylus arm 32 is pivoted to an ear 34 of a swinging arm 35 which inturn is pivoted on a fixedpost 36. I

Arm 35 is made of spring steelor some other resilient material to affordthe required pressure between the stylus and record and still permit thestylus arm to be rocked clear of the record without necessitating anextra pivot or universal joint. lateral extension 35.1 coacting with arestoring cam member 37 on an oscillating shaft 38. When shaft 38 isrocked, the swinging arm is restored to normal position, after beingdriven along the record surface by engagement therewith.

For the. purpose of raising and lowering The arm 35 has a "as 1110cxionsion ongagcnicnt with has u out w inc swing- Thus,
